METHOD OF MANUFACTURING METAL CASTINGS

A method of manufacturing an aluminum alloy cylinder head includes providing a mold assembly including a gating system, a head deck mold, and a mold cavity. Liquid aluminum alloy is pumped at low pressure into the gating system of the mold assembly filling the mold cavity. Next, the head deck mold i...

Zusammenfassung:	A method of manufacturing an aluminum alloy cylinder head includes providing a mold assembly including a gating system, a head deck mold, and a mold cavity. Liquid aluminum alloy is pumped at low pressure into the gating system of the mold assembly filling the mold cavity. Next, the head deck mold is removed from the mold assembly and the head deck and combustion chambers of the cylinder head are quenched.
